Most people rush straight into writing a script or opening their AI video tool—and that’s usually where the chaos starts. Before you even think about dialogue, visuals, or prompts, you want to be crystal clear on two things: what this video is supposed to achieve, and where it will live. A 60-second TikTok explainer, a 5-minute YouTube breakdown, and a 20-second LinkedIn teaser all demand totally different creative decisions, even if they’re technically about the same topic.
A simple way to start is to answer three questions in writing: Who is this for (specific audience, not “everyone”)? What single problem, desire, or question am I addressing? And what action do I want viewers to take at the end (follow, click, sign up, comment, share)? Once you’ve written those in plain language, you’ve essentially defined the “job” your video needs to do. This becomes your north star whenever you’re making decisions about pacing, tone, or how deep to go.
What most people don’t realize is that your platform choice also quietly shapes your entire script to screen workflow. Vertical, fast-paced, hook-heavy videos for TikTok, Reels, and Shorts want a tighter structure, punchier edits, and bold on-screen text. YouTube, on the other hand, gives you more room to breathe, build context, and lean on visuals that develop over time. LinkedIn tends to reward clarity and authority, often assuming viewers might watch on mute for a few seconds before committing.
So, as part of your ai video production checklist, lock in these platform details up front: aspect ratio (9:16, 1:1, 16:9), ideal duration (15–30s, 60s, 3–5 min, etc.), and viewing conditions (sound-on, sound-off, autoplay). Write them at the top of your project notes. It sounds basic, but when you later ask an AI to generate scenes or edit cuts, you’ll have parameters that actually match where your video will be watched—rather than trying to fix a horizontal, slow-paced clip for TikTok at the last second.
